Hi,
In TestLoadIncrementalHFiles's runTest method, a hfile is created for each

Hello,
I did not find any clear documentation on this aspect: is it possible to
write from a co-processor that runs on a certain region server to a region
that falls within the scope of another region-server? If yes how does this
happen? Do the region-servers communicate directly?
A use case migh
Hi Sever,
Use the getTable() method of the given coprocessor environment. It gives you
access to any table in the cluster.

Hi,
What version are you using?
On trunk, put(Put) and put(List) calls the same code, so I would
expect comparable performances when autoflush it set to false.
However, with 250K small puts you may have the gc playing a role.
What are the results if you do the inserts with 50 times 5K rows?
N.
Hi all,
When I run MR jobs, I don't see data locality because the TT sees
/default-rack/c4n1.gbif.org but the TableInputFormat is
giving /default-rack/130.226.238.181 (the same machine) when it determines
the splits for the job.
Clearly we have set something up wrong - has anyone seen this? I've
Hi,
I have a problem with Hbase master, although namenode, and job tracker are

Looks like localhost is somehow resolving to an IPv6 address. If this is
not your intent (usually not recommended), then you can hint the JVM by
adding
-Djava.net.preferIPv4Stack=true to the HBASE_OPTS var in hbase-env.sh.
